Pope Caius

Pope Caius (240-22 April 296) was Pope from 283 to 296, succeeding Pope Eutychian and preceding Pope Marcellinus.

Biography
Caius was born in 240 to a family of Romans, and he was elected Pope in 283. Caius decreed that bishops had to first be priests and everything before then (deacon, sub-deacon, etc.), increasing the prerequisites for being ordained. Caius expanded new churches and cemeteries during his rule, and he baptized those converted by St. Tiburtius and St. Susanna. In 296 he took refuge in the Catacombs of Rome as Emperor Diocletian persecuted Christians, and he was martyred.
